"I feel very proud of what I have done, but I want to do more," Mata said.

"I want to win more trophies, for example the Premier League. It would be very special for me.

"It's the first time for a club to win the Champions League one season and the Europa League the following season.

"It's very difficult to do it in two consecutive seasons and I think we feel really proud of this team."

Brazil midfielder David Luiz shares Mata's desire for a Premier League title.

"We need to win titles," Luiz said. "This is a big club. Always you have the opportunity to play big games, play important competitions, so next year Chelsea want more Europe titles, want the Premier League, want everything.

"The team has a lot of quality that's why we won two big trophies in two years.

"The Premier League this season was a little bit bad [but] I think this team has a lot of quality for the Premier League next year."

If Chelsea are to mount a Premier League title challenge Mata and Luiz will be key figures and so too will Frank Lampard.

Lampard, who lifted the Europa League trophy at the Amsterdam ArenA after captaining Chelsea in the final, has signed a one-year contract extension at Stamford Bridge to end the uncertainty over his future.

Mata said: "He has showed this season, scoring 16, 17 goals, he's one of the best midfielders in the world."

Luiz's influence has grown under interim boss Rafael Benitez, who will leave this summer, so much so that he has been mentioned as a possible future captain.

"I just try to show my personality, just try to help my team-mates," Luiz said.

"I just try to be involved in the club, because I love this club, I love to play for Chelsea and I love football."

till I suppose it still gives him at least another year in the job. By the time it comes around , he can always make up another excuse. First it was 3 months , then a year .....Next year ? Whats his excuse with Van Persie ?
